17th May 2022 What is the difference between primed and unprimed skirting and architraves? Primed or Un-primed? Put simply, primed mouldings are those that have been coated with a primer before leaving our factory. After they have been installed, they then only need painting with your final colour. This is fast becoming the preferred option as it saves time and money for the end user. Extra lead time must be allowed for if you choose this option. Normally it will add only a few days to your expected delivery date.
